There are a few steps required to extract the data from the multipart zip archive under macOS. We successfully tested the solution mentioned [here](https://superuser.com/questions/365643/how-to-unzip-split-files-on-os-x). 

In the terminal do the following:

```bash
cd path/to/downloaded/zip/
zip -s 0 name-of-dataset.zip --out name-of-combined-archive.zip
unzip name-of-combined-archive.zip
```
